Synapse Carbon 4 Chalk

Road Reimagined

Go long, go short, go fast. This is WorldTour performance for real world rides.

Real world performance! Designed to go fast, built to go long, made to keep you comfortable, the Synapse redefines road performance. With a lighweight frame featuring wind-tunnel sculpted tubing and PB-blasting stiffness to weight, it's a bike that's ready for anything you demand of it. Just ask Lachlan Mortan why he trusted it for his record-smashing lap of Australia. Unreal speed, engineered for real-world roads!

Compliant comfort

 With advancements in our carbon layup, our engineers have made the new Synapse 20% more compliant than it's already butter-smooth predecessor, ensuring you feel 100% more comfortable even on the roughest roads.

Like a glove

A great fit and feel makes for a great ride. And with our Proportional Response Construction, every rider gets that as standard. From the carbon layup through to the geometry, everything on the Synapse has been tuned and tested by frame size, so that your bike works in harmony with you to give the best possible ride for you and your height.

Wireless brains meet all-road brawn

Synapse Carbon 4 runs Shimano 105 Di2 for a shifting experience that feels straight off the pro tour, minus the bank loan. The frame delivers that signature Synapse ride—quietly fast, endlessly composed—and plays nice with wide tires, fenders, and long days. Call it the sweet spot between Sunday speed and weekday practicality.

Bring it all, bring it on

Our all-new StashPort storage system in the downtube is there when you need it and hidden when you don't. Paired with it's StashBag buddy, you can bring along your ride essentials and know that they will be secure, whatever you get up to out there. Meanwhile, best-in-class tyre clearance lets you take the idea of riding for longer to a whole new level.

Big ride rubber

Best-in-class clearance for tyres with a maximum width of up to 48mm in the front and 42mm in the rear with at least 4mm of extra clearance on each side. This makes the Synapse a true, ride-longer, ride-whatever kind of road bike.
